All the Max Wedge cars and possibly some of the 1964 and 1965 race Hemi B body cars came stock with 7260 U joints work
As far as replacing the bolts make sure they are grade 8 and not to long up scope The straps are different between the 7260 and 7290 U joints also,don't try mixing them tsk Maybe replacing the front U joint with a Neapco H.D. solid truck U joint (no grease fitting in it up) will help make it live longer under abuse on the street also up scope
